In recent years, the dryer technology in China has been maintaining a steady state, there is no obvious development and changes. However, because the dryer is also a large energy consumer, with the increasingly tense energy, new energy-efficient dryers such as air-heating heat pump dryer, automatically adjust the baking time, smart dryer control type, etc. have been fast Promotion and popularization are also inevitable trends in the future development of the drying industry. The material drying process is a huge energy-consuming process. According to statistics, the energy consumed for drying in most developed countries accounts for 7%-15% of the national total energy consumption, while the thermal efficiency is only 25%-50%. And most of the drying process, especially for heat-sensitive materials (such as food and biological materials) will affect its color, nutrition, flavor and organization. The heat pump drying technology has the advantages of low energy consumption, small environmental pollution, high drying quality and wide application range, and its excellent energy-saving effect has been proved by various experimental research institutes at home and abroad. It is reported that the main principle of the air energy heat pump dryer used in the drying process is to use heat pump evaporator to absorb the heat energy in the outside air, or to recover the waste heat in the drying process. After the compressor work, the energy is transferred (transferred) to the drying In the dry box, the hot air in the drying box is heated repeatedly to absorb the moisture in the material and cool down and humidify itself. After the hot air removes moisture or condenses and removes water, the water in the material is drained away and the material is finally realized. Continuous drying. The air energy heat pump drying equipment has the advantages of energy saving and emission reduction, safety and environmental protection, good drying effect, high efficiency and energy saving, low operating cost, saving labor costs, wide range of use, and the like. At present, air heat pump drying has gradually been applied in many industries. Tongyi Air Energy is the leading brand in the air energy industry. Its high-temperature heat pump dryers have been applied in industries such as agriculture, industry, and textiles with energy-saving, high-efficiency, safety-free, and simple operation. Good comments from people and users. Now, the heat pump drying equipment has gradually replaced the traditional boilers, earth room baking, etc., and has become the middle of the drying industry.
